Application filed March 30,- 1926. Serial No. 98,551.

The present invention is concerned with the provision of an attachmentfor the head lights of automotive vehicles which serves the purpose ofpreventing glare without in any way minimizing the light thrown upon theroad.

A further object of the invention 1s to provide a device which willprevent the blinding rays of a head light from being thrown in the eyesof pedestrians, or the eyes of the drivers of approaching cars withoutdimming the light.

A further object of the invention is to provide an antiglare shield ofthis character which may be expeditiously and securely attached to anyordinary automobile head light without requiring the services of amechanic.

Further objects of the invention are to provide a head light attachmentwhich will not detract from the appearance of a car, an attachment ofsimple, practical construction which will be durable and efficient inuse, an attachment which may be manufactured with comparative economy,and an attachment which is universally adjustable to receive anystandard. size of head light caslI1 v IlVith the above noted and otherobjects in view, the invention consist-s in certain novel features ofconstruction and combinations and arrangements of parts, as will be morefully hereinafter set forth and pointed out in the claims. The inventionmay be more fully understood from the following description inconnection with the accompanying drawings, wherein Fig. 1 is a view infront elevation of an attachment embodying the present invention showingthe same in assembled condition.

Fig. 2 is a View in side elevation of Fig. 1, indicating in dot and dashlines a head light casing to which my improved antiglare shield isattached.

Fig. 3 is a perspective View of the shield assembled.

Fig. 4 is a plan view of the shield in the fiat condition in which it isshipped.

In the drawings a conventional type of cylindrical head light casing hasbeen indi cated in dotted lines at 10, and to such cas ing the antiglareshield attachment of the present invention may be readily secured.

In Fig. 4 I have shown the appearance of the attachment before it isassembled on the head light. It will be noted that it includes asubstantially triangular shield or plate portion 11. Plate 11 as amatter of fact is in the form of a regulartrapezium having one parallelside 12 so short, that the plate is of'approximately triangular shape.At the corners of the longer parallel'side of the plate, I pivotallyattach, as by a rivet 13, the ends of bendable metallic head lightclamping bands 14 formed with a series of screw or bolt holes 15 intheir free extremities. Under the shorter opposite side of the plate 11there issecured a'pivot bolt 16 to the ends of which are pivoted theends of substantially rigid bracing bars 17. Near their free ends thesebars are formed with longitudinally extending slots 17* for purposes-ofadjustment, as will be later described.

The plate 11 is of flexible bendable metal so that the longer parallelside thereof may be transversely bent to conform to-the curvature of ahead light casing, and so that the reduced forward end thereof may bebent downwardly on the transverse fold line indicated at 18.

In assembling the device upon the head light casing, the longer parallelside of the plate 11 is transversely bent as best seen in Figs. 1 and 3to conform to the peripheral curvature of the casing 10.. The bendablestraps 14 are wrapped or bent about the casing 10, and the end portionswhichwould overlap turned at right angles to provide depending aperturedextensions 19'. The section of the plate 11 forwardly of the line 18 isthen bent downwardly until it just conceals the lamp bulb (not shown)disposed at the center of a light casing from the View of one directlyin front of the head light. The two rigid bracing bars 17 are then swungrearwardly andasecuring device such as a screw or bolt 20 passed throughthe aligned slots 17 in the bracing bars and a pair of aligned apertures15 in the extremities 19 of the clamping bar 14. The bars 14 are of sucha length that they may embrace any standard size of head light and leavedepending extremities 19 of greater or less length in accordance withthe size of the head light. The slots 1 in the bars 17 permit axialadjustment of these bars to pull the forward end of the shield 11downwardly to the desired extent. With the screw 20 in place, theantiglare shield is firmly locked against vibration independently of thehead light casing.

In practice the under face of the plate or shield 11 will be ofreflecting material. The upper face of the plate 11 and the outersurface of the clamping bars 14 will be painted in conformity with thecar to which the device is attached, and the bracing bars 17 may bepainted, nickeled or otherwise treated in accordance with the taste of auser.

With the antiglare deflector in place, the forwardly and downwardlyinclined end of he glare shield will screen the light source from theeyes of the drivers of approaching cars. Light from the main body of theplate 11 will be reflected downwardly on to the road and forwardly ofthe shield.

Various changes and alterations might be made in the general form andarrangement of parts described without departing from the invention.Hence I do not wish to limit myself to the details set forth, but shallconsider myself at liberty to make such changes and alterations asfairly fall within the spirit and scope of the appended claims,

I claim:

1. A. glare shield attachment for automobile head lights including abendable vizorlike tapered plate adapted to have its transverselycurved. rear edge secured to a head light casing the rear portion of theplate belug parallel with the central longitudinal axis of the casingand including a bendable tapered forward extension adapted to screen theforwardly projected horizontal rays of a light in the casing, said.extension being bent forwardly and downwardly at a sharp angle andterminating below the plane of the central longitudinal axis of thecasing.

2. A glare shield attachment for automobile head lights including abendable vizor-like tapered plate adapted to have its transverselycurved rear edge secured to a head light casing and including a bendabletapered forward extension adapted to screen the forwardly projectedhorizontal rays of a light in the casing, said extension being bentforwardly and downwardly below the plane of the central longitudinalaxis of the casing, means for rigidly attaching the forward end of theextension to the casing, including a pair of inclined bracing bars, andbendable casing embracing straps secured to the rear end of the plateand adjustably detachably engaged at their ends with the rear end of thebracing bars by a common securing device. I

3. A device of the class described in claim 2, wherein the casingembracing straps include downwardly turned ends having aligned openingstherein. and the bracing bars have longitudinal slots aligning with saidopenings to adjustably receive the coinmon securing device.

4. A glare shield attachn'ient for automobile head lights including abendable plate shaped as a regular trapezium and havinga transversebending line parallel with the parallel edges thereof, the longerparallel edge of the plate being adapted to be bent around a head lightcasing, so that the larger end of the plate will constitute a vizor,that portion of the plate between the bending line and the shorterparallel edge being bent forwardly and downwardly below the plane of thecentral longitudinal axis of the head light casing to screen directforwardly presented rays of light from the casing.
